An engine vibration damper with a heat dissipation structure

Abstract

This utility model discloses an engine vibration damper with a heat dissipation structure, belonging to the technical field of engine vibration dampers. It includes a damper body, with a mounting plate slidably installed inside the damper body. Two rotating rods are mounted on the mounting plate via bearings. A handle is installed at the end of each rotating rod, penetrating the damper body. Two gears are mounted on the rotating rods. In this engine vibration damper with a heat dissipation structure, rotation of gear one drives gear two to rotate, which in turn drives a screw to rotate. The screw rotation causes a threaded movable block to move along a guide rod. The movement of the movable block causes a fixed block and a cooling box to move synchronously. During the operation of the cooling box, vibrations occur. By cooperating with a torsion spring, the cooling box oscillates slightly around a rotating shaft, allowing for free adjustment of the cooling box's position, thereby increasing the heat dissipation area and preventing damage to the engine body.

Description

Technical Field

[0001] This utility model belongs to the technical field of engine vibration dampers, specifically an engine vibration damper with a heat dissipation structure. Background Technology

[0002] Engine dampers are devices that reduce engine vibration, consisting of elastic elements and damping components. Their function is to absorb the vibration energy generated during engine operation, reduce the transmission of vibration to the vehicle body, decrease noise, prevent component wear, and improve driving comfort and safety. They are widely used in engine systems in automobiles, machinery, and other fields.

[0003] Currently, engine shock absorbers are typically equipped with heat dissipation structures to ensure the internal engine temperature. However, existing heat dissipation structures are usually fixed inside the engine shock absorber and cannot be actively adjusted in position. When the engine is running at high power, heat tends to accumulate locally and is difficult to dissipate quickly, which can easily damage the engine body and increase costs. Utility Model Content

[0004] To overcome the above-mentioned defects, this utility model provides an engine vibration damper with a heat dissipation structure. This solves the problem that currently, engine vibration dampers are usually equipped with heat dissipation structures to ensure the internal engine temperature. However, existing heat dissipation structures are usually fixed inside the engine vibration damper and cannot be actively adjusted in position. When the engine is running at high power, heat tends to accumulate locally and is difficult to dissipate quickly, which can easily damage the engine body and increase costs.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an engine vibration damper with a heat dissipation structure, comprising a damper body, a mounting plate slidably mounted within the damper body, two rotating rods mounted on the mounting plate via bearings, a handle mounted at the end of each rotating rod penetrating the damper body, two gears mounted on the rotating rods, four screws mounted between the damper body and the mounting plate via bearings, two screws forming a group, a gear being mounted on each screw, the gears meshing, a moving block threaded onto each screw, four guide rods fixedly mounted on the mounting plate, the moving blocks slidably connected to the guide rods, two fixed blocks fixedly mounted on each moving block, a rotating shaft rotatably mounted between the two fixed blocks, a connecting block mounted on the rotating shaft, two torsion springs sleeved on the rotating shaft, and a cooling box mounted on the connecting block.

[0006] As a further embodiment of this utility model: a protective cover is installed on the shock absorber body, a plurality of ventilation openings are provided on the shock absorber body, and an engine body is fixedly installed on the mounting plate.

[0007] As a further embodiment of this utility model: four limiting grooves are provided on the body of the shock absorber, and a sliding rod is fixedly installed in the limiting groove.

[0008] As a further embodiment of this utility model: two buffer springs are sleeved on the slide rod, and two limiting blocks are slidably installed on the slide rod.

[0009] As a further embodiment of this utility model: a connecting rod is hinged to the limiting block, and a support rod is installed at the connection point of the two connecting rods.

[0010] As a further embodiment of this utility model: a support block is hinged to the support rod, the support block is connected to the mounting plate, and a plurality of telescopic rods are installed on the damper body, the ends of the telescopic rods being connected to the mounting plate.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] 1. This engine damper with a heat dissipation structure, consisting of a handle, a rotating rod, gear one, and a screw, operates by first opening the radiator box and then turning the handle. The handle rotates the rotating rod, which in turn rotates the two gears mounted on the machine. Since gear one and gear two mesh, the rotation of gear one drives gear two to rotate, which in turn drives the screw to rotate. The screw's rotation causes a threaded moving block to move along a guide rod. This movement of the moving block causes the fixed block and the radiator box to move synchronously. During operation, the radiator box vibrates. In conjunction with a torsion spring, this causes the radiator box to oscillate slightly around the rotating shaft, allowing for free adjustment of its position and increasing the heat dissipation area, thus preventing damage to the engine.

[0013] 2. This engine vibration damper with a heat dissipation structure, through the installation of a mounting plate, support rod, slide rod, and limiting block, works as follows: When the engine body is working, it will generate vibration. The pressure generated by the vibration will be transmitted downwards, through the mounting plate to the support rod and support block, and then through the support rod to the connecting rod. Since the connecting rod is hinged to the limiting block, the limiting block will move along the slide rod, thereby compressing the buffer spring. The buffer spring, under compression, generates a restoring elastic force, which will be transmitted upwards through the limiting block and counteract the pressure generated by the vibration, thus playing a role in buffering and damping vibration and improving the stability of the device.

[0020] The technical solution of this patent will be further described in detail below with reference to specific embodiments.

[0021] like Figure 1-5 As shown, this utility model provides a technical solution: an engine damper with a heat dissipation structure, including a damper body 1, a protective cover 2 installed on the damper body 1, a plurality of ventilation holes 3 opened on the damper body 1, and an engine body 4 fixedly installed on the mounting plate 5. Because the protective cover 2 is installed, external dust and impurities can be prevented from entering the interior of the damper body 1, so as to avoid affecting the operation of the engine body 4.

[0022] The damper body 1 has four limiting grooves 6, and a slide rod 8 is fixedly installed in the limiting groove 6. Two buffer springs 10 are sleeved on the slide rod 8, and two limiting blocks 9 are slidably installed on the slide rod 8. Because of the buffer springs 10, when the engine body 4 is working, the pressure generated by the vibration will be transmitted to the connecting rod 11 through the mounting plate 5. Since the connecting rod 11 is hinged to the limiting block 9, the limiting block 9 will move along the slide rod 8, thereby squeezing the buffer springs 10. The buffer springs 10 generate a restoring elastic force when squeezed, and the elastic force will be transmitted upward through the limiting block 9 and cancel out the pressure generated by the vibration, thus playing a role in buffering and damping vibration and improving the stability of the device.

[0023] A connecting rod 11 is hinged to the limiting block 9, and a support rod 12 is installed at the connection of the two connecting rods 11.

[0024] A support block 13 is hinged to the support rod 12. The support block 13 is connected to the mounting plate 5. Several telescopic rods 7 are installed on the damper body 1. The ends of the telescopic rods 7 are connected to the mounting plate 5.

[0025] A mounting plate 5 is slidably installed inside the shock absorber body 1. Two rotating rods 18 are mounted on the mounting plate 5 via bearings. The ends of the rotating rods 18 pass through the shock absorber body 1 and are fitted with handles 21. Because of the handles 21, the rotating rods 18 can be rotated. The rotating rods 18 drive two gears 19 to rotate. Since gears 19 and 20 mesh, the rotation of gears 20 can drive the screw 15 to rotate. The rotation of the screw 15 causes the threaded movable block 17 to move along the guide rod 16. The movement of the movable block 17 causes the fixed block 24 and the cooling box 14 to move synchronously, allowing the position of the cooling box 14 to be freely adjusted to prevent damage to the engine body 4.

[0026] Two gears 19 are mounted on the rotating rod 18. Four screws 15 are mounted between the damper body 1 and the mounting plate 5 via bearings. Two screws 15 form a group. Gears 20 are mounted on the screws 15. Gears 19 and 20 mesh. Moving blocks 17 are threadedly connected to the screws 15. Four guide rods 16 are fixedly mounted on the mounting plate 5. The moving blocks 17 are slidably connected to the guide rods 16. Two fixing blocks 24 are fixedly mounted on the moving blocks 17. A rotating shaft 22 is rotatably mounted between the two fixing blocks 24. A connecting block 25 is mounted on the rotating shaft 22. Two torsion springs 23 are sleeved on the rotating shaft 22. Due to the installation of torsion springs 23, vibration will occur during the operation of the cooling box 14. By cooperating with the torsion springs 23, the cooling box 14 will swing slightly around the rotating shaft 22, thereby increasing the heat dissipation area.

[0027] A heat dissipation box 14 is installed on the connecting block 25.

[0028] The working principle of this utility model is as follows: When the engine body 4 needs to be cooled down during operation, the operator first opens the cooling box 14 and then turns the handle 21. The rotation of the handle 21 drives the rotating rod 18 to rotate, and the rotation of the rotating rod 18 drives the two gears 19 installed on the machine to rotate. Since gear 19 and gear 20 are meshed, the rotation of gear 19 will drive gear 20 to rotate. The rotation of gear 20 will drive the screw 15 to rotate. The rotation of the screw 15 will cause the moving block 17 connected to it to move along the guide rod 16. The movement of the moving block 17 will drive the fixed block 24 and the cooling box 14 to move synchronously. During the operation of the cooling box 14, it will vibrate. In cooperation with the torsion spring 23, the cooling box 14 will swing slightly around the rotating shaft 22.

[0029] When the engine body 4 is working, it will vibrate. The pressure generated by the vibration will be transmitted downwards, through the mounting plate 5 to the support rod 12 and the support block 13, and then through the support rod 12 to the connecting rod 11. Since the connecting rod 11 is hinged to the limiting block 9, the limiting block 9 will move along the slide rod 8, thereby squeezing the buffer spring 10. The buffer spring 10 will generate a restoring force when squeezed, and the force will be transmitted upwards through the limiting block 9 and cancel out the pressure generated by the vibration.
